.RETAINING DEVICE FOR WINDOW-SASH.

T0 allwho'm it may concern;

Be it known that I, 'WILLIAMM. DUoKER, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Retaining Devices for VVindow-Sash, of lowing is a specification. u

This invention relates. to a retaining device for window sash and the object thereof is to provide a simple, efiici'ent devicewhich will serve to maintain the window sash'in any adjusted elevated position, without. the

use of weights or other counterbalancingi devices.

A furtherobjectis to'soarrange and con,

struct the parts ofthedevice that they'may be manufactured and assembled- .at small; cost, and so-that the completed device may be correctlyattached to a'window sash b a minimum of labor and care. v Other objects and aims of the invention,

more or less specific than those referred to above, will be in part obvious and in part pointed out in the course or the followingdescription of the elements, combinations, arrangements of parts and applicationsof principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification,

and in which I have shown a. merely pre ferred form of embodiment of the invention:

Figure 1 is an elevational view of a win dow illustrating this invention applied to the sash thereof. I Fig. 2 is an enlarged View of a part of the sash broken away to disclose the manner; in which the supportingdevice is attached thereto.

Fig. 3 is a front elevational view of the supporting device detached. Q

Fig. 4 is a transverse sectional view taken upon the plane of line IV'-IV of Fig. 3.

I Fig. 6 is a fragmentary top plan view illustrating the manner of connecting certain portions of the device together 5 and v Fig. 7 is a transverse'sectional view taken upon the plane of line VII-VII of Fig. 6. Referring to the drawings for a detailed description of the structure shown therein,

the. reference character L indicates the window frame and G the sash thereof. The supportlngdevlce is indicated generally by the reference character .H. In Fig. 1 two sash are-lllustratedand each of these is provided with two of the su porting devices, one at eachs -de thereof. ,ince allof the support- 1ng dev cesv are identical in construction and arrangement, one only will be described in detail. It will be understood also that one supporting device may be employed upon each sash, if desired, instead ofthe two illustrated. In fact, a single supporting device 15 all that is necessary for small windows.

The supporting device comprises essene tially a basemember 1, a friction roller2, a spring 3 resiliently connecting the roller wlth the base. member, and a pawl 4 arranged to prevent rotation of the roller in one direction. 5 r

The base member is preferably formed of angle shape, as shown in Fig. 2, having a vertical leg 5 arranged to engage the-edge surface ofthe Window frame, and a horizontal leg 6,'at the lower end-of the vertical leg, projecting into. a recess 7 formed in the windowsash. A screw 8 may be employed to connect the vertical leg with the material of the sash.

reference numerals9 and 10 in Fig. *3. The

coils-are spaced somewhat from thepoint Where thelegs are connected to each other so'as to comprise a straight portion 11.= This end portion 11 is disposed to lie fiat against the under surface of the leg -6 of the base member and may be fixed thereto in any suitable manner.

Preferably. the manner of fi-xing'the portion 11 to the leg'6 of the base member includes a depressed section-12 of the material of the leg 6 so as to forma'recess or pocket 13into which the portion 11 extends. After, the end. of theportion 11 has been'inserted within the recess 13 the material of the section 12 is pressed upwardly between the spaced legs of the portion 11 so astodivide the recess 13 into-two independent holding pockets. By this means a firm andzefiicient fixed to the base member. If desired, the end portion 14 of the leg 6 may be bent down so as to prevent longitudinal-movement of;

- the portion 11 in one direction. .Longitudr" are'conti nued downwardly andare' formed with eyes 16'at their lower ends constituting journal bearings for supporting the roller 2,v the roller being provided with axle 'extensions 17 engagingwithin the eyes 1:6 for this purpose, a

When in use, the roller '2is held back within the-recess ofthe window 'sash by engagement with the surface 18 of the" win dow frame L, as shown in *F ig 2. t The't'en sion of the spring 'is continually urging-the whieh'are arranged to be engaged by a tooth roller into tight frictional engagement with thesurface 18; I l v The roller 2 is provided with a ratchet surface "19 at one side thereof, the/teeth of.

20 'formed asapa'rt'of th'e pawl .4 son-as to prevent-rotation of the roller in a clock-wise direction.

The pawl 4 is preferably though not necessarily, made froi'nsh'eet metal-and is providedwith a relatively'largefiat body portion 21=apertured aS at 22 to receive one of the :axle extensions 17 of the roller." The broad 'flat body portion is intended to lie .1 normally flat against the side of' 'the roller" between-the toothed'portion '19 ofjsaid roller, and the adjacent end 23 of'the coiljspring 9.

The tooth 20 is formed at the "upper end ofthe body 21, and above said tooth the body is formed with a pair of laterallyfex-I tending spaced fingers24: arranged ,to lo'o selyand slidably and rotatably engage'about the leg 23.- k i The aperture 22 is elongated to facilitate the i g movementof the body longitudi' nal'lyof the leg 23 to permit the tooth 20 to move upwardly forreleasing the teeth of the portion 19 I when the window sash is being raised but to permit the tooth to "move "downwardly into engagement with one of th'c" teeth f po n 19 when'the-window sash is being lowered, oris'in'an elevated at rest position. r I V The space between the surface 1 ofi'the toothed portion 19 and the end 23 ofthe' spring is somewhat greater than thethick! nessof the body: portion 21, and theaper ture 22 islsu fiiciently large, so'that the body portion '-is permitted a limited, orloose swinging-movement about an axis 'substa'n ti'ally parallel to the length ofthe leg 23 of the spring, as clearly indicated bythe dotted L linesip ,ig. of the drawin The rear surfaces of the teeth of the portion 19 preferably have their outer corners beveled off, as at 25,50 as to more readily swing the body 21 into the position shown by the dotted lines in Fig. 4 and to thereby more readily, free the tooth 20.

The wide part 26 0f the body will engage the surface :of the portion 19 of theroller to retain the tooth 20in engaging position at all times.

- It W111v thus, be, seenthat thetooth 20 disengages the teeth of the portion 19 by either an upward movement or by aside swing ng movement. The object .in'f, providing the two means for disengagement is so as to' avoid any (possibility of a' failure of the tooth to disengage 'itself. Either or both means of disengagement 'may be brought intoplayat any time and eachis practically independent"oftheothei. V v

"It will be? understood, of course, that the resilientfpressure exerted by the j roller against the window frame will retain the sash againstpossibility of rattling at all times.
